Automatic paper feed device

Abstract

The invention provides an automatic paper feed device which is used for feeding paper. The automatic paper feed device comprises an upper cover; the upper cover is provided with a fixing device, a first absorbing component arranged on the inner surface of the upper cover, and a paper taking module arranged below the inner surface of the upper cover; and the paper taking module comprises a paper taking arm which can be rotated to a preparation position or a paper taking position, and a second absorbing component arranged on the paper taking arm. When the paper taking arm is positioned at the paper taking position, paper feed operation is carried out; and when the paper taking arm is rotated to the preparation position, the second absorbing component absorbs the first absorbing component tomake the paper taking arm fixed at the preparation position. The paper taking module of the automatic paper feed device in a sleeping or power-saving state is fixed at the preparation position, so that phenomenon that paper cannot be fed or multiple pieces of paper are fed can be avoided.
